There are many finishing materials on the construction market, but water-based paint holds the leading position. This is dictated by its competitive advantages
:
- The absence of odors and toxic impurities makes the coating safe and harmless.
- The paint dries quickly.
- You can get any color by mixing the primary white shade with the color.
- If you use a textured roller when painting, you can imitate the pattern of expensive designer wallpaper.
- To use water emulsion, you do not need special knowledge and skills.
- If the surface gets dirty, the splashes can be easily washed off with water.
- The paint has high decorative characteristics: it creates a pleasant matte finish that does not glare or wear off.
- Adding various substances to paint increases its wear resistance.
In this article we will talk about how to paint various surfaces with water-based emulsion correctly and without streaks. We will also reveal little secrets that will help you make repairs quickly and accurately.
Preparatory work
The final result depends on the quality of wall preparation. The surface to be painted must be cleaned of old materials. This could be whitewash, wallpaper or oil paint. Only after this should the wall be perfectly leveled.
Removing old whitewash and paint
If there was previously a thick layer of whitewash, then you need to make a large number of shallow cuts on the treated area, and then thoroughly wet the entire surface with warm water. In this state, the wall should stand for about half an hour, after which it is necessary to wet the coating again and wait until it is completely wet. After the procedures, the whitewash can be easily removed with a spatula. Then the walls are washed with a regular sponge. It is not necessary to apply incisions to thin layers.
Old water-based paint can be removed in the same way. Much more difficulties arise when removing oil paints and nitro enamels. Sometimes a construction hair dryer serves as an assistant, with the help of which the painted surface is heated, and then the used material is scraped off with a spatula.

Using a hair dryer is ineffective when removing old materials. It will be a waste of time to use this method of getting rid of the old coating. There is a technology for washing with chemicals. This procedure is quite unpleasant and can harm the respiratory tract. To avoid poisoning, you need to open the doors and windows in the room to create a draft, and if possible use a respirator and rubber gloves. Apply the solvent to the coating with a rag, wait the time specified in the instructions, and wash off the old paint. The process is repeated several times until the base is completely clean.
There are also mechanical ways to remove old coatings. The simplest method is sanding walls manually or using a grinder. You can use a drill with various attachments.

Puttying and priming
As already mentioned, the entire area to be painted with water-based paint must be brought to perfect smoothness; cracks and roughness are not allowed. To eliminate roughness, the walls are puttied.
To identify weak points, the suspected areas are carefully inspected, tapped with a hammer, and doubtful areas with cracks are picked out with a spatula to remove small fragments from them. The resulting large potholes are plastered with a solution based on a cement-sand or gypsum mixture. After drying, proceed to direct leveling. Step by step it will look like this:
- Padding.
- Applying starting putty.
- Final putty.
- Grinding (sanding the surface) with a grinding machine, a special mesh or sandpaper.
The primer serves for better adhesion. In addition, the procedure helps reduce the consumption of other materials, and the paint will lie evenly. Drying time for the primer is approximately 6 hours. It is usually indicated in the instructions for the material. You can also recognize the complete drying of the walls after applying the primer by touch.
Advice! The primer is applied with a roller. It is preferable to prime in two layers. The second layer can be applied after the previous one has completely dried.

Types and characteristics of water-based paint
Among the varieties of this type of finishing it is worth highlighting:
- acrylic;
- silicone;
- silicate;
- polyvinyl acetate.
Water-based mixtures on the walls quickly become ready. This usually takes about a day. Paints dry in 20 hours, sometimes in less than 10, in some cases in more than 48 hours. Compositions that meet GOST do not emit a pungent odor, are easily amenable to the movements of tools, acquire any shades and maintain an intact surface for a long time. The viscosity of solutions is adjusted depending on the application method: with a brush, materials with an indicator of 40-45 units are used, and with a spray gun - 20-25. The paint is applied in one or several layers, and an average of 250 grams is used per 1 m².
Polyvinyl acetate solutions are considered the “weakest” option. Although they are cheap and are better suited than others for wooden and porous coatings, they do not tolerate moisture well and are inferior to other varieties in terms of durability. Acrylic mixtures are an expensive and high-quality version of water-based paints; silicone compositions claim to be the “golden mean”, but silicate ones, if properly selected, will be an ideal solution in rooms with normal conditions.
Acrylic water-based paint
This is what is used most often. Solutions are made from acrylic resins with additives as inclusions. For example, a latex additive allows paint to be used in areas exposed to water. Painted surfaces can be washed without fear that the quality of the coating will deteriorate.
Acrylic water-based mixtures are also applied to walls with a difference of up to 1 mm and randomly located roughness. As for surface types, acrylic options are the most versatile and are compatible with plastic, wood, concrete and even glass. Among all types of water-based compositions, acrylic is best suited for metal coatings, not least because it has anti-corrosion properties. It also dries better than others. Just a few hours are enough to begin subsequent manipulations. Due to the high price of conventional mixtures, manufacturers also produce paints with acrylic copolymers.
Silicone water-based paint
The material is used in damp rooms, as well as in rooms where moisture forms. The listed uses are suitable for these solutions due to the fact that the silicone base gives them high vapor permeability. Mold and mildew do not grow on surfaces painted with silicone paint. The reappearance of these microorganisms will also not threaten walls and ceilings. At the same time, in terms of resistance to water, the mixtures are inferior to acrylic ones.
Among the positive qualities are plasticity, strength and ease of use. The cost of silicone mixtures is difficult to count as an advantage, but the price-quality ratio has contributed to its spread on the market. Water-based paint with silicone-based components hides cracks and depressions up to 2 mm in diameter. Silicone solutions are considered a cross between acrylic and silicate.
Silicate water-based paint
The emulsion is made from liquid glass and coloring additives. Raw materials have low cost and long service life. Silicate paint withstands temperature changes well. Mixtures that are resistant to natural phenomena can last 2 decades without updating. There are modifications for sale for interior and exterior decoration, as well as universal solutions - they are classified depending on the severity of their properties.
The coating painted with a silicate mixture absorbs air in which there is excess moisture. In rooms that are too dry, the surface will release moisture. With all this, raw materials cannot be compared with silicone, because the latter is used in places where the walls and ceiling are constantly exposed to moist air. The glass-based variety is suitable for the facades of houses near which there are high groundwater levels.
Wall painting
Water-based paint is rightfully considered an environmentally friendly material for finishing apartments and houses. A large assortment of colors allows you to choose the right color to create any interior. There are many application methods. Using textured rollers allows you to even change the texture. The design options cannot be compared with anything. The basic rule when painting walls with water-based emulsion is compliance with all proven technologies and application sequence.
To ensure that the painting process does not take too long, and the result will only please you, you need to make sure in advance that you have good construction equipment on hand.
In order to successfully paint walls with water-based paint, you need good tools and materials:
- roller with handle;
- brush;
- bath or tray;
- electric drill with attachment;
- film for covering the floor to protect against splashing;
- dye;
- color.

Preparing for work
The paints that come from retail outlets have a thick consistency. To obtain the desired degree of viscosity, add a little water. Mix the composition with a drill equipped with a mixing attachment. There is no need to dilute the paint with water to create a textured surface.
After mixing, the paint is given the desired shade. For this purpose, various colors are available for sale. You can choose the tone yourself by combining colors in different proportions. In large retail outlets, computer shade selection is carried out using special installations. When preparing it yourself, remember that the color changes slightly as it dries.
The paint is diluted for the entire area at once, so as not to have to worry about tinting later; it will be difficult to manually select the same tone.
Application of water-based paint
Typically a roller, sponge or paint brush is used for this purpose. The texture depends on which tool is chosen.
Painting walls with water-based paint using a roller is the fastest and most convenient way. The second advantage is that the paint is applied evenly with a roller. The layers are thin.

Advantages and disadvantages
Water-based solutions pose no threat to human health or nature. None of the known types of paint contain toxic or other hazardous substances. The raw materials do not emit a sharp unpleasant odor that consumers feel when painting with other types of solutions.
As soon as the water evaporates, the craftsmen begin the next stage of work. Manufacturers promise very fast drying, but in reality you have to wait even a day or more. Still, it's relatively fast.
Compositions based on aqueous emulsion are given any color without exception. A construction mixer and additional amounts of pigments are used for this. Even an inexperienced person can achieve pure colors. With all this, a decent palette of ready-made solutions will immediately open to the buyer.
The material is washed with water; no solvents are used. Hands and tools will be clean in less than a minute.
Water-based solutions also have disadvantages. It is worth highlighting 4 key disadvantages:
- poorly suited for glossy and metal surfaces;
- water-based compositions are easier to counterfeit;
- apply easily, but not as evenly as thicker paints;
- they are often overused.
Technology
Work starts from the top. This start will prevent streaking and ensure uniformity. Following the recommendations of professionals, the entire area is mentally divided into squares. Their number depends on the size of the roller: one square is equal to five times the width of the nozzle.
The working area is additionally divided into 5 verticals, the first line is skipped and the second strip is painted immediately. Then they skip the third vertical, moving directly to the fourth. Finish at the fifth line. Then you can move on to the remaining runs: the first and third.
The second layer of paint is applied in the reverse order: start with the third line, then paint the first, fourth, fifth. The finishing line should be the second stripe.
After completing the painting work, the drying process begins. The duration of setting depends on the temperature and humidity in the room. To speed things up, you can open a window. It is strictly forbidden to do this in winter.

Work equipment
You won't need too many tools, here's the full list:
- Pallet. It is desirable that it be equipped with a special ribbed platform, which is used to uniformly impregnate the roller and remove excess water emulsion.
- Roller. The best option is a nozzle with artificial fur or medium-length bristles. Professionals recommend using foam rubber and velor rollers in other cases.
- Telescopic handle. You may need it to work without climbing on a stool or stepladder.
- Masking tape. It will be very useful if the ceiling is already painted and needs to be protected from accidental brushstrokes. You can also use it to create simple and complex geometric patterns or to delimit areas that you plan to paint in different shades.
- Brushes. Wide (about 8 cm) and flat - for painting corners and joints of walls and ceilings, and a narrower brush, which is convenient for getting around sockets and painting hard-to-reach places.
- A special whisk or corresponding attachment for a drill. They are needed for mixing paint.
A good painting tool will make the job much easier.
Creating textured surfaces
Sometimes water-based compositions are used to obtain a textured surface. To do this, take a thick mixture that is not diluted. It is applied to the walls with a stiff bristle roller, lint-free roller or foam sponge. The rigid structure of the pile allows you to fill existing pores on the wall. The second step is to grout the protruding parts with a lint-free roller or foam rubber. The use of solutions of other shades is allowed.

How to choose correctly
Sellers may not differentiate between water-based and water-based paints. This is the first difficulty, and it can be solved simply: the packaging must contain the inscription “water-based”.
Surfaces in apartments get dirty quickly, especially with greasy stains, so you should choose washable options. Of course, if this factor does not become limiting. The paint packaging should be checked for compliance with GOST. There are not enough marks on the packaging; you need to ask for a certificate. The process of making water-based compositions itself is not very difficult, so fakes come across more often than in the case of other paints. Complex equipment and specific substances that are difficult to obtain are not used in production. This is good for the price, but in terms of quality assurance you will have to be vigilant. In addition to the listed criteria, it is worth paying attention to the specifics of consumption and the intended purpose - for interior or exterior work.
Application Features
Knowing some secrets will help you paint walls with water-based paint yourself:
- When preparing the composition, you need to immediately calculate the amount that will be sufficient for the entire room. Otherwise, finding the same shade will not be easy
- The walls are painted in one go. This is the main condition for quality finishing.
- To paint corners and small details you will need a small brush, no more than 5 cm wide.
- Excess paint is immediately wiped off on the edge of the pallet, otherwise it will leave streaks on the walls.
- The mixture is applied to small areas from top to bottom.
- Before starting work, the baseboards, window sills, and ceiling (if it is already painted) are insulated with masking tape. Masking tape is also used to mark boundaries. It is removed immediately after painting the area. Once the paint has hardened on the tape, it is almost impossible to remove it without damaging the wall.
To get a good result, you need to have a creative approach to the process, correctly distribute your forces and show imagination.
How to choose a color
Assortment of tinting agents:
- color with a metallic or pearlescent sheen;
- universal pastes for enamels;
- concentrates with a liquid consistency;
- pigment pastes.
Universal coloring pastes are suitable for epoxy, nitrocellulose and polyurethane enamels. Pigment is used with wood and lumber.
For water-based emulsions, the maximum content of coloring pastes and colorants is about 20%. At the highest rate, the saturation will be maximum, and the treated coating will not suffer from chemical exposure.
The pigments themselves for tinting are of natural or inorganic origin. The first group has a brighter and deeper color, but compositions with them do not have high light resistance. The surface will be unprotected from exposure to alkalis. Natural colors include umber, lapis lazuli, ocher, manganese, etc. Artificial dyes like carotene or rhodopsin give the mixture high light fastness, but leave much fewer color options.
Before purchasing, you should find out what the final result will be, and for this they use special catalogs. Exceeding the permissible concentration will lead to a change in the properties of the paint, and if the content is too low, the raw material will have to be stirred frequently.
Briefly about the main thing
You can independently finish walls with water-based paint if you follow known rules and developed technologies. Important emphasis is placed on the choice of tools. It is necessary to calculate the area of the walls to determine the amount of material. Color and tinting can be selected at retail outlets on the computer. However, you can do this yourself manually. It should be remembered that the tone changes as the paint dries.
High-quality preparation of the surface to be painted is 50% success. To avoid streaks and gaps, the work is carried out in stages in several layers. Each new layer is applied only after the previous one has dried. Speed of work is also important due to the rapid setting of materials.
If all conditions are met, a good result is guaranteed.

Required Tools
Most often, the compositions are applied to the wall with a roller. There are several types of this tool that are used to paint walls with water-based paint without streaks:
- Foam rubber. The simplest and cheapest type, but due to the fact that foam rubber absorbs a large amount of the composition, microscopic bubbles can form on the surface. It is better to opt for a roller with a high density.
- Velor. Such products are difficult to find in non-specialized stores. Velor is a dense material, so it absorbs a relatively small amount of paint. Thanks to this feature, the tool practically does not splash the composition, but it needs to be dipped in paint quite often.
- Fur. In this case, we are talking about rollers made of natural or artificial fur. There is practically no difference between them, only natural ones last longer. This option is considered traditional for painting walls.
With the help of a simple tool, you can create different coating textures.
It is also important to determine the size of the tool. In most cases, it is better to choose the longest possible rollers to make the painting process faster. But before buying, it is better to weigh the tool in your hand and take into account that paintwork will make it even heavier.
In addition, painting with water-based paint requires brushes for treating hard-to-reach places, a painting tray with a grooved surface, and a mixer for stirring the material. You also need to prepare a stepladder in advance if the ceilings are high, and work clothes.
Decorative properties of colorful coatings
The execution technique will be considered improved if all the recommendations of experts are taken into account. And they say that during the work it is necessary to completely eliminate drafts and not to thin the enamel too much, since this is not economical. You can paint walls with heavily diluted acrylic paint, but it will lose its quality.
Modern design has a whole arsenal of expressive means that can give the interior a unique image. Of course, everything depends on the chosen finishing materials, texture, color and other factors.
If you do the interior with your own hands, then you need to take into account that water-based paints are produced in white. They can be given a colored tint using special colors. You need to choose a color before starting work. The amount of tinted mass must be calculated for the entire volume at once. If there is not enough of it, it will be difficult to choose the right color and shade. Often even an automatic machine cannot cope with this.
Additional colors change the composition of the paint, but only slightly; the performance characteristics remain the same. You don't have to worry about products with improved formulas at all.
Coloring ideas
In the photo of painting the walls in the bedroom there is often a combination of several colors. When choosing color options for the bedroom, you need to take into account the wishes of the owners, the architectural features of the room, and the existing furniture. Most often you can find these types of wall painting:
Horizontal division of walls. The parts can be divided equally or the bottom part can be 2/3 narrower than the top. The border can be left as is or decorated with a border.
Colored inserts. To do this, paint the wall in a neutral color. Then markings are made using molding, and the inside is painted with a more saturated color.
Striped walls. The stripes can have any direction. The main thing is that they are not too narrow. Stripes of the same color, but of varying degrees of saturation, look noble.
Accent. If you want to add some freshness to your bedroom, choose a central wall and paint it a bright color. This technique is often used by designers.
Roller selection
Rollers are available in various types. Such diversity is necessary to apply different types of solutions. They can also paint different areas. To choose the right tool, it is worth understanding their purposes.
To choose the right tool, it is worth understanding their purposes.
Size
The size of the roller is selected taking into account the area of the room. Thus, the following types of rollers are distinguished according to their dimensional parameters:
- Mini ones are suitable for processing small areas, in corner areas, when using stencil types. Rubber options are suitable for securing seam areas to improve the quality of wallpapering;
- Midi is used for many types of work, for covering ceilings, floors and walls. If you choose the right fur coat, you will be able to use the device many times;
- Maxi, it is difficult to control the evenness of the base coating with them; they are usually used for treatment with a primer solution, or for the 1st layer of painting, if it is meant to be covered with another layer of finishing material.
The size of the roller is selected taking into account the area of the room.
Foam rubber
The foam type is distinguished by its high-quality impregnation of coloring compounds. Can be selected for many substrates, intended for water-based paints, varnish products or adhesive solutions.
It is prohibited to use this roller for water-based emulsions and oil-based products; the components included in the paints have a detrimental effect on the foam base.
The foam type is distinguished by its high-quality impregnation of coloring compounds.
Velours
Suitable for ceiling areas or applying a finishing agent. You can use a velor roller to treat water-based and oil-based compositions, but keep in mind that they are poorly saturated, for this reason you regularly have to re-paint the velor coat.
Suitable for ceiling areas or applying a finishing agent.
Polyamide
They can withstand thinners in paints, so they are considered universal. They are well absorbed by the composition and release it to the surface. They are easy to clean and can be used several times for this reason.
They can withstand thinners in paints, so they are considered universal.
Fur
The layer is distributed evenly, and even wall defects are filled. The length of the pile allows you to cover the entire base with high quality. They do not splash when rolled; can be chosen for treating large rooms.

Elimination of serious defects
The solid base does not need to be removed. Sometimes, to save the situation, it is enough to carry out a series of simple manipulations, after which you can be confident in the reliability of the intermediate layer. Most often, the integrity of the coating is compromised by cracks. How to get rid of them?
- We “expand” the crack – we increase its dimensions – width and depth. You will need a chisel, hammer and spatula.
- We clean the resulting depression from dust and pieces of plaster using a brush.
- We prime the improvised “gorge” using compounds with maximum penetration ability.
- Fill the hole with putty using a spatula.
- We glue the reinforcing material - press it into the putty layer, coat it and leave it until completely dry.
- We sand the restored area.
It makes sense to carry out spot restorations only if the amount of damage does not exceed 25% of the wall area.
Puttying with finishing putty
The finishing putty has a finely dispersed structure and forms a perfectly smooth base. It will not help to hide serious defects. Therefore, it is only good in combination with a starting mixture, provided that the base is properly prepared. If the finished material is too thick, dilute it with water. It is very convenient to work with white putty on a gray base, since areas where there is not enough material immediately become visible. It is necessary to form an opaque and dense coating. Two layers will be enough.
A color scheme
Often, when decorating bedroom walls, two or more colors are used.
The color combination can be of three types:
- Mixing different shades of the same color;
- Combining similar colors, for example, pink and peach;
- Using contrasting colors (blue and muted orange, etc.)
Goethe's color wheel will help you decide which combinations are best to choose.
